6. Optionally, go to the Group settings tab and specify the widget settings:

   • Apply button: Adds a widget button which applies the values of all selectors in the widget. The selector values are not applied until you click the button.

   • Reset button: Adds a widget button which resets the values of all the widget selectors to their defaults.

   • Auto height: Sets the automatic height for a widget on the dashboard. Available for widgets with multiple selectors.

   • Optionally, for a widget with multiple selectors, use the Show in tabs field to configure how to display the selector on the dashboard:

     • Current tab <tab_name> is default. The selector will be displayed on the specified tab.
     • Selected tabs: Select one or multiple tabs where you need to display the selector. By default, the current tab is selected.
     • All tabs: Display the selector on all tabs.

     This setting becomes available when you add a second selector to a widget:

     • Setting value used in the first selector automatically applies to the entire group. You can change it at any time.
     • For each new selector in the group, the default value is From group settings <group_value>.

     When using this setting, consider the following:

     • You cannot save a selector if it has the setting value where the current tab displays no selectors. For example, if you specify Selected tabs for a single selector, you can deselect the current tab, but you cannot save the selector.

     • You cannot save a selector with the Selected tabs value if no tabs are selected.

     • Group settings restrict how you set up each selector within a group. For example, if you select Current tab for a group, you must also specify Current tab for each selector in this group.

       Configuring a group	Configuring a selector
       All tabs	Current tab, Selected tabs, All tabs
       Selected tabs	Current tab, Selected tabs
       Current tab	Current tab

     • When you delete a selector on the current tab, it is automatically deleted from all tabs.

     • When you copy and paste a selector, its settings are preserved.

     • You cannot paste a copied selector if its settings prevent it from being displayed on the current tab.

   • Optionally, for a widget with multiple selectors, customize the selector arrangement. To do this, arrange the selectors as needed by dragging them and adjust the width of each one:

     • Auto: Automatic selector width.
     • %: Selector width as a percentage of the widget's total width.
     • px: Selector width in pixels.

   Click Save.

   

7. Click Save. The widget will be displayed on the dashboard.

LimitationsLimitations

• For measure selectors, only one type is available: Input field.
• We recommend that you always make your measure selectors independent from other selectors. To do this, set your dashboard's link type to Not linked with other selectors in the Links section when editing.
