Filter Elements Overview
The Web Dashboard allows you to create three types of filter elements that provide the capability to filter other dashboard items.
To add the required filter element to the dashboard, use corresponding buttons into the Filter section of the Toolbox.

The Combo Box dashboard item allows you to select a value(s) from the drop-down list.
You can switch the combo box type in the Combo Box's Options menu. The table below demonstrates available Combo Box's types.
