Drupal 8 - How to hide help link About text formats and text format guidelines

Problem

In drupal textarea field, it was always a pain to see the two links:

• Text format showing list of available format, even if user is allowed to use one format only
• And a link of About Text formats

Solution

Drupal 8 provided an easy but hidden way to hide this. Do following steps:

• Goto your content type
• Click on Manage Form Display
• For example, body is the field
• Click on settings icon button on right hand side of body field
• A small form will open up

• Check on option - Hide the help link About text formats
• Check on option - Hide text format guidelines
• Save the content type
• Clear cache and open the form

See the final form

Perfect Solution

Note: You did hide the two unwanted options in the form. But, you can still see the drop down of formats. This should be fine for most of the users. But, I did not want this. I did not want to confuse my users.

Install module Allowed Formats Do following steps:

• Goto your content type
• Edit the field, example body field
• In edit form, you will see a section of Allowed Formats

• Select your desired format. I selected Full Html
• Save the form
• Open your form, and you will see only your text area.

Hope it helps.
