Create Value Help 
Value help, also known as input help, selection help, or F4 help, is the offering, typically in a pop-up dialog box, of possible valid values for an input field. Visual Composer includes functionality for creating two different types of value help:
Value Help Entry Lists (Design-time Value Help)
You can create reusable selections of values that are made available as entry lists. You can then use these lists while designing your model to, for example, supply valid values to a formula. This is provided in conjunction with the Entry List function described in Create an Entry List.
Value Help in Your Model (Run-time Value Help)
You can integrate value help into your model. When you do this, you add a button next to an input field that displays a dialog box that lists valid values. This helps a user select the right, properly formatted value to enter into the field.
You configure this type of value help with the value help wizard. The wizard creates the button and an embedded iView that models the value help functionality.
