Query Editor: Show selected values in top of the drop-down list.

In the Query Editor, we would have great value with a Select All choices or showing selected values in the top of the menu.

Example:
Our users creates a query, where multiple values are checked off.

After working with the items in the work area, the user want to edit the query, de-select either some or all of the selected values.
But the user has to scroll all the way through the list, to de-select the selected (or search for the specific value)

Our idea, is to either highlight the selected values in the top of the menu – or have a “Select All”, where the user then click this twice, to select all first, and then remove all afterwards.
Just like it is an option on the Details page, if the field type is CVL, and if its MultiValue.

Example of an already existing “Select All” option, in a CVL drop-down menu.

Example of an idea, where the selected are shown in the top of the menu.
