Configuration options for layouts

Applicable to Theme UI-Kit applications

Learn about the layout configuration options that you can use to customize your layout. For example, you can specify the format, the visibility of the layout, and the source of data for dynamic layouts.

The layout configuration options are available on the General tab of the Properties panel and are arranged in the following table in alphabetical order.

The options in the Pagination, Identifiers, Container settings, and Accessibility sections are presented in the order in which they appear on the Properties panel. The availability of options depends on the layout type, the context in which the layout is placed, and other options that you select.

General options

Field Description Available for
Active when Specifies a condition that determines when a layout that is nested in another layout group is activated. The following layouts, when they are nested in a Layout group:
  • Dynamic layout
  • Layout group
  • Repeating dynamic layout
  • Dynamic layout group
  • Table
  • Hierarchical table
  • Navigational tree
  • Columns
Caption Displays a header or a label for a layout that is nested in another layout.

You can configure additional settings for the header, for example, a type or a heading level. For more information, see the Container settings table.

  • Dynamic layout, when it is nested in another layout.
Container format A container determines the background color, border, text style, heading, and padding of the layout. Apart from the default options, you can apply a custom container format that is defined in the skin, by selecting Other, and then specifying the custom format in the adjacent field.

For more information on how to create a skin, see Component style formats.

  • Dynamic layout
  • Layout group
  • Repeating dynamic layout
  • Dynamic layout group
  • Columns
Create grid dynamically

Creates a dynamic column in the table that is sourced from a report definition. At run time, the table generates the columns that are displayed in the way that it is set up in the report definition. The run-time display of the table automatically updates when the report definition changes; you do not need to update the section that contains the table.

You can add static columns before and after the dynamic column in the grid.

You can select additional settings in the Specify virtual report definition option.

This option is available only when you select the Report Definition option in the Source field.
  • Table
Defer load activity Runs an activity that is called when loading more data is required. This option is useful when loading all the available data at once when the layout is first rendered on the screen might take a long time.
This option is available only when you select the Property option in the Source field.
  • Hierarchical table
  • Navigational tree
Defer load contents Delays loading the content of the layout at run time until the user clicks an element on the page.

This option improves the first loading time of the page.

If you want users to take actions on a work item, for example, submit a from, when the remaining content on the page is still loading, you can configure sections to use defer-loaded asynchronous declare pages.

  • Dynamic layout
  • Repeating dynamic layout
  • Columns
Display grid footer Displays a footer below the table. The Display footer list provides options to select when the footer is visible.
  • Table

You can configure additional settings for the header, for example, the type or the heading level. For more information, see the Container settings table.

  • Dynamic layout
  • Layout group
  • Columns
Display message when there are no rows to display Displays a message about the lack of rows to load when the data set from which the layout sources data is empty. You can select a section or a field value that contains the message text that you want to display.
  • Repeating dynamic layout
Enable adding new tab Provides users with an option to add tabs at run time.
  • Dynamic layout group
Enable numbered accordion For the Accordion option, this parameter activates automatic numbering of collapsible headers.
  • Layout group

Specify a pre-loading activity Specifies an activity to run before loading, when the container is expanded by a click. This activity can compute property values and other aspects of the container that is expanded. As a best practice, create a defer-loaded wrapper section with the retrieval activity, instead of multiple defer-loaded sections with wrapper activities.
This option is available only when you select the Defer load contents option.

Specify custom results page

Provides an option to define your own clipboard page to store the results of running the Obj-List-View, Obj-Browse, and RDB-List methods. The following options are available:

By name
The table uses the pagination format that is configured in the custom results page of a report definition that you specify.
By property reference
At run time, when the property is resolved, the associated clipboard page is used.
This option is available only when you select the Report Definition option in the Source field.
  • Table
Specify virtual report definition

Uses the pagination format of a report definition set as a source of data for the layout. The following options are available:

By name
The table uses the pagination format that is configured in the report definition that you specify.
By property reference
The table uses the report definition in the clipboard page, rather than the report definition that is specified as the data source. With this approach, you can display columns that are hidden in the report definition, hide columns that are visible, or make subtle changes to the presentation. For this option, you must specify a virtual report definition page, which is a clipboard page of type Rule-Obj-Report-Definition.
This option is available only when you select the Report Definition option in the Source field, and then select the Create grid dynamically option.

Pagination

Paging divides content into segments, which is helpful when a table contains more than 20 rows of data. By specifying options in the Pagination section, you can control the loading of data on a screen. Pagination options fall into the following categories:
Traditional paging
Retrieves a data set segment on the clipboard. You can specify the number of rows per page and select a page navigation control format. The paginate gadget (the pyGridPaginator section) is automatically added to the right-most cell in the Action Top section of the table. You can drag the gadget onto any cell in an action area, except for the repeating area.
Users can access data through the paging controls, and they can drag rows within a page. If the results produce less than one page, the paginate gadget does not appear at run time.
Progressive paging
Limits the number of rows that load when a user accesses the layout to render the page more quickly. The remaining items are loaded as the user scrolls through the list. Progressive paging enables users to access the entire data set by scrolling. Users can perform operations on the full data set by dragging the rows to re-order the list and by sorting and filtering the entire list.

For a working example of the paging options, see UI Gallery landing page. You can access paging examples in the See also column to the right of the Table sample.

Pagination

Field Description Available for
Pagination format Defines the format of pagination.
None
No paging.
Page 1 of X (traditional paging)
Presents a page number and a total page count. Users open a page by editing the number and pressing Enter, or by using the navigation buttons.
Page 1,2,3... (traditional paging)
Presents the first group of links as page 1, the second group as page 2, and so on. Users open a page by clicking a number. The display is limited to 10 pages. If there are more than 10 pages, users click (...) to advance to the next group.
Rows 1 - Y (traditional paging)
Presents a range of rows in a drop-down list. Users open a page by selecting a range from the drop-down list or by using the navigation buttons.
First X Results (traditional paging)
Presents a defined set of rows and a total row count. For example, if the setting is 50 and there are 200 rows on the clipboard, a label at the top of the list reads Showing 50 of 200.

Users can access the whole data set by clicking Show All, and then reorder data by dragging the rows.

Progressive (progressive paging)
Presents one page of data that contains the number of items that the Page size list specifies. The remaining data is loaded incrementally.

Users can access the whole data set and perform any actions, such as re-ordering data by dragging, sorting, and filtering.

Performance of large data sets is influenced by a variety of factors, for example, the row contents and the end user system. When you use a large data set, sort and filter options instead of paging, provide users with a specific set of rows.
As defined on report definition
The page format is the same as in the report definition.
  • Table
  • Hierarchical table
  • Navigational tree
Progressively load on user action Retrieves a page from the data set on the clipboard. You can specify the number of rows on a page and select a page navigation control format.

Additional data displays as the user clicks on the page navigation control. The users can access the entire data set.

This option works only when the underlying harness is configured to use the client-side template UI.
  • Repeating dynamic layout
Progressively load on scroll Limits the number of rows that load initially to render the page more quickly. The remaining items load as the user scrolls through the list. The users can access the entire data set.
This option works only when the underlying harness is not configured to use the client-side template UI.
