I have created a control in the designer and now I want to use it in the application builder. How do I use it?
All control build on designer are available on the builder by default (if they are not disabled explicitly).
You can do the following to check if the control is enabled.
Click on the edit control properties icon on the top right (pencil icon).
Check the Status and deprecated properties are set as show below.
The control is published with the latest version.
If all these steps are followed, The control should be visible on the left control panel.
