Add character counter for HTML fied in Catalog item

[ashu1612]

I am trying to create a catalog items with some HTML fields with restriction  of 300 characters minimum. Now I need to implement a character counter which tells users how many characters they have filled. could you please help me how to achieve this without affecting other html fields in system. I know there are some out of the box property but enabling them will affect all other html or multiline field in system.

Hi @ashu1612 ,

Using the onChange catalog Client script, you can implement it.
