A textarea doesn’t seem like the right place for more/less.
There are so many ways to achieve this dependent on the dataset being shown - If you’re using p tags to show content, perhaps previously captured via a textarea, then the code you’ve shared looks fine and can be re-used in Wappler using the same JS/CSS or simply using Bootstrap dynamic attributes (Show)
What amazing community wappler has with everyone willing to help.
Thanks @AdrianoLuiz I am actually portuguese so this is perfect
Thanks @web-works but I am trying to make half text visible and the other half with a toggle.
Thanks @scalaris I will try it, my only doubt is how to divide the dynamic text in two !
