Text fields can be used for a variety of things. You can add Names, Descriptions, and anything that could be a combination of letters and numbers like IDs, codes, etc.
There isn't a character limit for this field type, however, if you are looking to save large strings of text, we recommend the Note Field instead, you can learn more about this field type in the following tutorial:
Configuring a Text Field
Give your field a name and add a field hint if desired. You can then select the section in which the field will be created or keep the default option.
For this field, on top of the field hint, you also have the option to add a help text that describes the expected values of the field. On the form, your team members will see an 'i' that will display the help text when hovered over.
The field type must be set to 'Text'.
If desired, you can set a default value for all new records. Team members will have the option to override the default value if needed.
Text fields can also be calculated. Just enable the 'Calculated' checkbox and add your custom code in the space available for it.
Enable the 'Required' checkbox if the information for this field is mandatory. It means that if you enable this option, every time a team member creates a new record, they will need to input text on this field in order to save it.
If you enable the 'Lock After Create' as its name implies, the field will be locked once the new record is saved and the value of the field will not be editable afterward.
Text fields can be set up as 'unique'. This means that the system will prevent duplicates of the Text values from being added to the system. It is recommended to set up the Text as a Unique field if there shouldn't be any duplicated records with the same information in the Text field. It helps prevent that team members add different records with the same Text information twice.
Once you are done setting your field, click the save button.
Note: All new fields are added at the bottom of the form.
