I want to add some validation while adding new page from Add configuration >> Page in liferay in admin mode
There are two way
1. Direct add page from Add configuration mode and added page will appear as a text field to give some name.
2. After adding page when we are going in edit mode and after click on current page then again this page name open in text field
so I want to put the allow only 20 character enter in this text field and allow only character '_' and space
Here I am trying a lot to search is there any js code to override or something else but not able to find the solution.
Please help thanks in advance...
