What solutions have you tried so far? Did you look for solutions on the Developer Hub?
ContextActionService and priority binding, but nope didn’t fix it
Also if you’re curious, I’m making a autocomplete for a lua editor for use in my plugin, RunLSC (there was demand so I decided to try since I was also interested on doing this)
I’m not sure if it is possible yet to do this with native TextBox inputs. What you can do is use a TextLabel instead and manage everything yourself, or temporarily deactivating the TextBox. You can also try disabling MultiLine and registering inputs without checking if it was processed.
