Hello everyone. I have built a simple app that filters and searches through a gallery (Sharepoint List Datasource). The "Category and Sub-category are cascading dropdowns as each Category could have multiple subcategories. I have the app programmed to default to "All" on the category dropdown so that all categories can be seen simultaneously. I did this by adding this code to the App "Onstart" field.
The collection then populates the Category dropdown, giving the "All" option that displays all categories.
Here is the code in the "items" Property of the gallery.
Here is an example of when "All" is selected in the Category Dropdown. (The subcategory dropdown appears when anything other than "All" is selected)
My issue comes when I select a certain category from the Category dropdown, I would like to create and default to an "All" option at the top of the dropdown for each subcategory once a category is selected in order to avoid it auto choosing the first value in the subcategory dropdown (In this case its "IRA". Basically, I would like to allow a user to see all subcategories in the gallery for a certain category when chosen. Like so. Does anyone have any ideas, workaround, advice? Thanks a lot!
