You can set up a business rule that will make certain elements on record pages visible or hidden under specific conditions. These elements include: fields, details, field groups and tabs.
Case
Show the [Sick leave, days left] field on a request page for all requests whose [Originator type] is an employee.
To implement this, you need to make the [Sick leave, days left] field visible only if the value in the request [Status] field is “In progress.” To do this:
1.Open the needed section (e.g., the [Requests] custom section) and add a new business rule.. You can learn more about adding and setting up a new business rule in the “Customize page business logic” article.
2.In the “IF” block of the business rule, set the filter to define the conditions for triggering the business rule. For example, to apply a rule to the requests with the “Employee” originator type (Fig. 1):
a.Click [Add condition].
b.In the field that appears, select the “Originator type” column as the lookup value. Note that boolean fields cannot be used for setting up the condition since they equal either “true” or “false,” i.e., they are always filled in.
c.Leave the “=” (equal) sign as it is.
d.Click the 
icon and select the “Lookup” field type in the drop-down list. A set of fields for specifying lookup values will appear to the right. Select “Employee” as the lookup value from the drop-down list.

3.In the “THEN” block of the business rule, set up the action that would implement the needed business logic (Fig. 2).
a.Click [Add action] -> “Show element on the page.”
b.In the [Which element will be shown?] block, select the element type to show. For example, leave the [Field] element type as it is.
c.Select field to display on the page, e.g., [Sick leave, days left].
d.Click [Apply] -> [Section Wizard] -> [Save].

As a result, the [Sick leave, days left] field will display only for requests where the [Originator type] field contains “Employee.” If the [Originator type] field contains any other value, the [Sick leave, days left] field will be hidden.
