What is the difference between an uneditable and an editable combo box? Which of these is a combo box by default?

Short Answer

Expert verified
Answer: The main difference between an editable and an uneditable combo box is that the editable combo box allows users to type in their own input or edit existing options from the list, while an uneditable combo box only permits users to select from the provided list of options without any modifications. By default, a combo box is uneditable, offering a more controlled range of choices for users and ensuring valid input within the expected options.

Step by step solution

01

Define an uneditable combo box

An uneditable combo box is a user interface element that allows users to select an option from a predefined list of options. In this type of combo box, users are not able to type in their own input or modify existing options. They can only choose from the provided list.
02

Define an editable combo box

An editable combo box is a similar user interface element that also allows users to select an option from a predefined list of options. However, unlike the uneditable combo box, users can manually type their input or edit the existing options in the list. This gives more flexibility to the user, as they are not restricted to the predefined list of options.
03

Illustrate the differences between an uneditable and editable combo box

The main difference between the two types of combo boxes lies in the ability of the user to modify the list of options. In an uneditable combo box, users can only choose from the provided list of options, while in an editable combo box, users have more freedom to enter their own input or modify the existing options.
04

Identify the default combo box type

By default, a combo box is uneditable because it only allows users to select from a predefined list of options without allowing any modifications or additional inputs. This offers a more controlled and specific range of choices for users and ensures that the input will always be valid and within the expected options.
