How to add custom form element in "Text" field?

When I put my custom HTML form code in  source code of 'Text' element and save it. It does not show text box, dropdown box. 

Please note that it is not possible to display any form element in "Text" field. But why do you want to add add form fields in "Text" field? Even if you are able to add, you will not be able to capture any data in those fields. You need to add regular built in form fields (under form elements tab) to be able to capture submission data. You may like to take a look at the following guide which should help you:  https://www.jotform.com/help/46-Quick-Overview-of-Form-Fields

Hello Sir,

Thanks for the immediate reply.

Importing a web form by putting url of the web page is a good way for accessing the direct form.

But, is any other way, that I can able to use already created HTML code for the form which is on my laptop and not hosted. In short, I want to copy and paste my HTML code into any type of editor. And How can I do that?

Thanks.

If you are looking at adding your own HTML code in the Text field, then, it is possible. You can add HTML source code inside the Form Builder.

You can use the text field and then click on source code option, wherein you can add your HTML source code. When you add Text field to your form click on Edit HTML option and then click on Source code icon. 

Hope this will help. Let us know if you need further assistance.
