I cannot delete a selected entry in a map parameter in the Selected Activity pane.

We expect to have activities with ~10-100 entries in a map parameter, and we want these to be editable. Shown below, the "-" button (to the right of "Components") only deletes the last entry (as far as I can tell):

So, if I wanted to delete the first of 100 entries, I would need to delete the entire list of 100 entries.

I suppose we could work around it by adding a "N/A" or something to the dropdown (i.e., to the enum definition) indicating that the entry should be avoided, but that could get messy.

This may apply to list parameters too -- I didn't test.

Describe the feature request

I would like to be able to delete a specific/selected entry of a map parameter in the Selected Activity pane.

Clicking on an entry could highlight it such that the "-" button applies to it. At this time, clicking folds the entry. There are other ways to do this, and there are other issues motivating a redesign (#1057 , #490 ).
