Conditions for displaying fields

Good afternoon. There is a task - to display the N-th number of fields, only if the field X contains the desired value (s) Y (Z, etc.). The X field is a pop-up multilist. Now we have a choice of the following conditions: equal, Not equal (for some reason with a capital letter, although all other conditions are with a small one), less and more. To implement the task, there are not enough conditions: contains and does not contain. Those. the display condition will look like this: Hide the specified N fields if the X field does not contain the Y value.
