When you are creating a (custom) Field for your database, you have a few choices for the Input Type.
Outlined below, is a brief description of each available type of field which you can create, and an example as to how that type of field appears when you are coding.
Pick a date using a drop-down calendar. Since the dates are not added until the time of coding, you don't need to add any values. This is useful when sorting dates since dates in a freeform field will be sorted alphanumerically.
Enter any text you choose into a blank. Since it's freeform, you don't need to add any values.
A list of values to choose from, plus an "Add New" option for when your value is not (yet) in the list.
A list of values without an "Add New" option. This is useful in the event that you need to create a list of values, but want to prevent further editing or adding of additional fields.
Freeform field that expands to display longer inputs (e.g. Attorney Notes or Document Summary). Since it's freeform, you don't need to add any values.
A list of values to choose from, allowing a user to select more than one applicable value.
Type in or select a value, then click to Add. Click the x to remove a value. To add new values, go to your settings and add them in to your hot fields.
Set a single value (e.g. Hot Doc).
