The tricky thing here is determining when D1 would not have any choices. As you’re, I assume, in a normal form, the previous dropdowns’ values would be sandboxed inside the form. My suggestion is converting this to a custom form if it isn’t too much to build again. Write the choices to user-specific columns, so you can know on the fly where choices are available or not, and structure your submission availability around that. > [@How do I create a custom form?](https://community.glideapps.com/t/how-do-i-create-a-custom-form/25014): > > I’m just dropping this here so I have something to refer people to when they ask. 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 particular… There would also be a case where a user enters a choice (when D1 has available options), but then previous dropdown values change, leaving D1 with no options. In such cases, I would have a live list of available options for D1, and check if the chosen value at that moment is included in the list. Only validated if it’s included. --- _[View the full topic](https://community.glideapps.com/t/required-choice-component-behaviour-when-hidden/83702)._
