MCPE/Bedrock Form Tags
Generate server forms (like on Hive, etc.) with a website and send them to the player using the tag command in-game. Respond to button presses quickly and easily with command blocks. Requires Beta APIs experiment to be enabled.
With this add-on, you can generate server forms using https://formgenerator.xfinnbar.repl.co/ and display then in-game with the /tag command.
Enable Beta APIs.
Apply the behaviour pack and load the world.
Go to https://formgenerator.xfinnbar.repl.co/ and fill out the options.
Copy the command at the bottom and press enter.
Voila! You have your form.
