Answer:
To keep a dropdown list in an e-form, you need to ensure that the list items are entered as options in the form field properties. Here are the general steps:
1) Open the e-form in the appropriate software or application, such as Adobe Acrobat or Microsoft Word.
2) Select the form field that you want to turn into a dropdown list.
3) Open the form field properties window.
4) In the form field properties window, select the "Options" or "Dropdown List" tab.
5) Enter the list items that you want to include in the dropdown list, one per line. You can also use the "Add" and "Remove" buttons to add or remove items from the list.
6) If you want to allow users to enter their own text in addition to the predefined list items, check the "Allow custom text entry" option.
7) Save the changes to the form field properties and save the e-form document.
By following these steps, you should be able to create a dropdown list in your e-form that stays in place and allows users to select from a list of predefined options.
