DatePicker format on fields
On some date fields, when you enter the date you get the popup calendar that allows you to select a date. I notice on other date fields, it’s just a free-form text entry.
Is this a general setting in preferences, or is there more to it?
The free-from date fields are probably custom fields. Navigate to Customization >Lists, Records, & Fields and edit the field you wish to change. Update the field type to Date. HOWEVER, changing the type of a custom field will delete all of the existing information that is saved to that field. You need to run a saved search and export all of the existing records along with their values to Excel. Once the field type is updated, you can import back to that field to re-populate the correct data.
