Good day all~!!!

How to search for a text in a Webview?

my design is…

I am beginer and using thunkable-x.
I want to show people several pages and search for words that people want to find so that they can find out which page it is on.

** Jane answered me : Thunkable components are not able to interact with the data displayed on in a web viewer.

no way???

Are there any block samples?

Please help me??

Can you further explain your idea. There is a newly released component to interact with webpages.
