Hi Glide Community,
I am making an app for a consultancy firm. I am making a form where the students can select any one preferred country to study and then select UPTO 3 universities in that country. **If I do a dropdown menu with multiple selections, how do I limit them to select just 3 universities out of 100s of universities?**

how do you do a drop-down menu? If from inline list… you can limit it by adjusting options:

yes I am doing it from an inline list. Limiting number of items will reduce the items shown. I want a limited multiple selection option.
For example:
I have a list of 10 universities. I want users to select not more than 3 universities based on their preference. If I limit the number of items to “3” then only 3 items will be shown in the dropdown menu.

then you gonna have to create a custom action, and a counter of selected items… (when the user click the item, set USC column to 1, another condition will be … if is 1 then set to 0, or clear the value), in that action do if-else condition if the counter is 3 then show a notification that “you can select only 3”

Yes, that is my second option. I think I will have to add row in the custom action as well, then make relationship to the original form and then do a joined list and look up for showing those selections in that form.
Was just hoping if there was a native solution for this.

you don’t need to add a row… just a USC column to mark selection… no relations are needed at this point

I think you have used the Trebuchet method right?

You can use a custom form.

This is a simple concept app (copyable), that demonstrates the following techniques: Building custom forms for adding and editing list items (as an alternative to the native forms provided by Glide) Preventing duplicate new entries using [User Specific Columns](https://docs.glideapps.com/all/reference/data-editor/user-specific-columns) and [Relations](https://docs.glideapps.com/all/reference/data-editor/computed-columns/relation-column) Enforcing mandatory input items The use of visibility conditions and user specific booleans to control user flow There is nothing particula…
Then I assume you story the university choices in a field called “Universities”.
Use a split text column to split that into an array and use a plugin to count the array length. It should give you the number to do some conditional visibilities.

For this case, I think the simplest option would be to use 3 separate choice components.

If you go that route, make sure you filter the choices so that you won’t get duplicate choices (I assume it’s not what you want).

Yes already filtered them out. Thanks for the suggestion anyways 🙂
