Using APEX 19.1 on RDBM 12.2
When I'm in the Page Designer, and I select several Columns (with Ctrl-Click) of an Interactive Grid, I can change properties of all of the selected columns at once. For instance, if select several columns that I want to be hidden or display-only, I see the Type Property in the properties editor. If all selected columns are currently Text Fields, I see that, or if there are different values for this property in the selected columns, it is blank. Then I can select "Hidden" in the dropdown, and all of the selected columns are changed to Hidden.
Has anyone implemented this functionality in their own applications? For instance, I have a column in the ATTACHMENT table called FILE_CLASSIFICATION_ID. The LoV for this column lets users choose Unclassified, Secret or Top Secret. I'd like them to be able to select several rows of the table and change all the classifications of selected rows in a single action.
