i want remove title field in any content type.
You want to either:


Remove the title field completely using the Fields UI. See this documentation page on the Fields UI. If you really don't want a title then just remove the field from the content type.
Use the Automatic Nodetitle module to create a title from a Token and hide the title in Edit Forms.
If not a Node, use the Automatic Entity Label module to create a title and then hide it from users in the Edit forms.


In general most content types need a title. Titles are the Names we give content to find them using Search forms and pages.
