About RichTextArea's img url

i want upload img in RichTextArea
like this:
when i click this button open a upload window rather than open a url
how to do it?


The RichTextArea component cannot be modified and does not support file upload dialog. You can either use it as is or consider using an additional FileUploadField.

we need the page like this
it can input text and insert img in the text
how to realize it?

We don’t have a component that implements such functionality out-of-the-box. You can find or create your own custom JavaScript component.
