How to add a title to a contact
For titles, you don't need to create a new Custom Field in your CRM.
It is already available in OnePageCRM; you just need to turn it on.
1
Go to your User/Profile icon (top right-hand corner) → Settings → Custom Fields tab.
Under Contact Fields, locate the Title field and toggle the slider to green to add them to your contacts.

2
To add additional drop-down values to the default ones e.g. Mr, Mrs, Ms, such as Doctor click on the pencil icon to the right of the Title Contact Field.

3
Add another field by clicking on + Add Item → add the new value → click Save to submit your settings.

4
To delete a dropdown option, click on the minus (-) icon to the right of the field → click Save to submit your settings.

5
In the contact view, you can select a title from the dropdown.
