### 8.9.7.4 Enabling Single or Multiple Row Selection

Enable single or multiple row selection and optionally display a row selector control.

Single or multiple row selections can be useful to facilitate bulk updates or other operations on the selected rows. You can create dynamic actions or server processes that act on the current selection. The primary keys of the selected rows can be made available in a designated page item by specifying it in the Current Selection Page Item attribute.

Tip:

The single or multiple row selections can be copied to the clipboard with standard keyboard shortcuts. On Windows: Ctrl+ C. On Mac: Command+C.

Tip:

The selection can also be accessed with the `interactiveReportRegion` JavaScript API.

The following example shows how to create row selector on a column in an interactive report built on `EBA_PROJECT_TASKS` table. The `EBA_PROJECT_TASKS` table is available in the Project Data sample dataset.

To enable single or multiple row selection in an interactive report:

1. View the page in Page Designer:
   1. On the Workspace home page, click the App Builder icon.
   2. Select an application.
   3. Select a page.
2. In the Rendering tab, locate the region containing the report and expand the Columns node.
3. Select the column to be configured as a Row Selector.

   The column Attributes display in the Rendering tab. In the Property Editor, edit the Column attributes:

4. Identification, Type - Select Row Selector.
5. Row Selection - Configure the following attributes:
   1. Row Selection, Enable Multi Select - Enables the selection of multiple rows. Turn on Enable Multi Select.
   2. Row Selection, Show Select All - If enabled, a Select All option displays in the column header and users can select all rows using Ctrl + A. If disabled, the Select All rows option does not display in the using a checkbox in the column header.
   3. Row Selection, Hide Control - Enabling this attribute, hides the checkbox or radio-control displayed on each row.
   4. Row Selection, Current Selection Page Item - Enter a page item used to store the selection state. This attribute holds information about all selected records and their primary key values and stores these values as a string separated by colons.

      In the following example, the `PROJECT_ID` column is selected and the following attributes are enabled: Enable Multi Select and Show Select All.

6. To save your changes click Save. To save and run the page, click Save and Run Page.

   If you run the page, the interactive report page displays with the check box displaying in the `PROJECT_ID` column. Note that a Select All check box also appears in the column header.

### 8.9.7.5 Formatting Columns in an Interactive Report

Customize column display with HTML expressions.

To define column formatting:

1. View the page in Page Designer:
   1. On the Workspace home page, click the App Builder icon.
   2. Select an application.

     `<span style="background-color: yellow; color: red;">#EMPLOYEE_STATUS#</span>`

   - Example 2: Use Heading 2

     `<h2>#EMPLOYEE_NAME#</h2>`

   - Example 3: Use a dynamic class from the SQL query

     `<span class="#COLUMN_CLASS#">#EMPLOYEE_STATUS#</span>`

     The `#COLUMN_CLASS#` and `#EMPLOYEE_STATUS#` substitutions in this example are columns selected in the report SQL query.

   - Example 4: Show an image, and a tooltip on hover

     `<img src="#IMAGE_NAME#" alt="#EMPLOYEE_NAME#" title="#EMPLOYEE_NAME#">`

   The next two examples demonstrate the use of template directives. To learn more, see Using Template Directives.

   - Example 5: Loop over a comma separated list of values

     `<ul>{loop "," TAGS/}<li>&APEX$ITEM.</li>{endloop/}</ul>`

   - Example 6: Use an "if" directive for a column with a quoted identifier

     `{if Mixed Case Name/}<strong>#"Mixed Case Name"#</strong>{endif/}`

5. To save your changes, click Save. To save and run the page, click Save and Run Page.

### 8.9.7.6 About Filtering on Conditional Links in Interactive Report Columns

Learn about about filtering on conditional links in interactive report columns.

If an interactive report has a column value that is a link and the link markup is constructed in the report query, attempting to define a filter on this value from the column header menu fails. Oracle APEX is not be able to render the link correctly in the column header menu because the column values are themselves rendered as links, such that they can be selected to apply the filter. If the developer wanted to conditionally render the link based on query logic, the link may have been defined in the report query as opposed to using the declarative column link support.

For filtering to work on conditional links in columns, developers have two options:

- Option 1: Use an HTML Expression column:
  1. Add another column to your query that selects the equivalent of the link text from the link and define a column alias of `my_link_display`. This column alias will be the value used in the column header menu.
  2. Change the `my_link` column to be of type Hidden.
  3. In the `my_link_display` column, set the column heading to be the same as the `my_link` column and set HTML Expression to be `#MY_LINK#`. Keep the default Escape Special Characters as Yes.

  4. Run the page.

     If needed, reorder the columns so that the new column in the same position as the old one. Select the Actions menu and then Select Columns.

  5. Save a new default report. Select the Actions menu, Save Report, and then Save as Default Report Settings.

  The link still renders fine in the report and the column header menu now renders just the `my_link_display` value which sets the filter correctly.

- Option 2: Use a custom Column Filter for the link column, where you could query for the link text.
