Listboxes are a very useful component when entering data on forms in databases. The proposal primarily concerns providing the user the ability to choose the list items of the listbox based on the values entered in the other fields and hide the deprecated values of the database list. Listbox provides the user the facility to choose from a list of choices, and on the other hand, ensures that the values entered in the field are appropriate. Hence, Listbox can be a quicker way to select a value from a list. Listboxes obtain the list items from the tables in the database, and sometimes it is not preferred to list all the items available.
