I recently encountered an issue with ComboBoxes. Within a gallery of items, I retrieved from SharePoint a multi-people field that displayed multiple items within the ComboBoxes. Upon expanding one combobox field I noticed that the sizing limitation was rather small and, although scrollable, annoying.
I would like to post an idea to add customizable functionality to enlarge / adjust the height of the ComboBox display selected items. In addition, I also noticed that when I made the font of the selected items text smaller or larger than default, the 'X' to remove a selected item did not dynamically increase or decrease in size.
