Choice Control


Choice Control allows creating a collection of radio buttons describing a set of related options. Only one radio button in a given group can be selected at the same time. Each choice option of the control has a configurable panel:

  1. Choice options (radio buttons)
  2. A panel of the selected option


The content of the Choice Control also depends on the selected view modes:

  • Radio buttons with Panel
  • Radio buttons
  • Selected Panel

Supported Layout Types

Choice Control can be used in the following Layouts:

Users with Administrator rights can change the default settings and add the control to other types of layouts via Supported Widget Types field in the Administration application → User Interface → Control Descriptors → Edit action → Advanced tab.

  1. Open the Layout Designer
  2. In the Toolbox, choose Choice Control
  3. Drag&drop the Choice Control on the canvas of the edited Layout
  4. Add necessary Choice Options
  5. Configure the Panels by adding and configuring necessary controls from the Toolbox:

    Disabled false and disabled true examples
    Instead of the static value, you can set the value from the Model. In this case, the choice option display mode depends on the value retrieved from a specified data model field.
  • Visible: by default is set to static value true and the option is shown; if set to false the option is not shown. Instead of the static value, you can set the value from the Model. In this case, the choice option visibility depends on the value retrieved from a specified data model field.

View Mode

Possible options:

  • Radio buttons with Panel (default): the control displays a list of options. When selected, each option has its specific configurable panel, for example, a panel where you can specify a Wizard:
  • Radio buttons: the control displays only a list of options. Only one option can be selected and in comparison to the previous View Mode the panel configuration is not suggested:
  • Selected Panel: shows only configurable properties from the selected panel. Radio buttons with choice options are not shown:

Defines the direction of the radio buttons alignment on the layout. Possible options:

  • Vertical (default): all choice options are aligned vertically.
  • Horizontal: depending on the screen size, the choice options are aligned horizontally:
    At the same time, the control descriptor content is responsive, and depending on the screen size the choice options are automatically adjusted and regrouped to a necessary number of columns to provide a better user experience.
    Additionally, the Horizontal direction allows defining the choice option Buttons Width. By default, it is set to 320px, but can be redefined and set in px, %, em or rem:

Control display modes:

  1. Static value: check-box options
    • selected (True): control displaying on the page layout template is enabled; 
    • disabled (False): the control is not shown on the page layout template.
  2. Model: select data model source out of suggested data with boolean type. The control displaying depends on the current value of a selected record.

Device Visibility


This property allows improving user experience by managing device visibility options.

For instance, the control can be hidden from the preview when it is too large and contains a lot of columns that cannot fit the small screen of a mobile device.

The application checks the user device's screen resolution and shows or hides grid preview based on the selected check-box options settings:

  • disabled: the grid is not displayed;
  • selected (default): the grid is shown on the page.
