Hi there,
I made a text entry as a required field in my app. Unfortunately, some users are using blank space to fill it up. May I ask for suggestions on how I can restrict blank space as an acceptable input?
Thank you.

Unfortunately, it looks like you would have to move to a custom form, trim your input fields and validate them there.

Hi @ThinhDinh may I ask how I can go about that? My current set up is I have a drop down list which is the “Supplier Name” if in the event that the supplier is not included in the drop down, they will be required to input a Name. Hence the issue with the blank space.
I did this set up because once they enter a new supplier in the text entry, the next time around it will automatically be incuded in the drop down list.

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…
