Deshabilitar edición de campos cuando éstos fueron pre-llenados desde una URL

Hola, tengo un formulario que tiene un campo de selección múltiple.

Quiero que cuando este campo haya sido pre-cargado desde una URL ya NO se pueda editar.

Cómo puedo condicionar los campos para que se sean modo Solo lectura, únicamente cuando fueron pre-cargados??

(si el formulario NO viene pre-cargado desde una URL, que SÍ se pueda editar)

Hi maya1tour,

Thanks for reaching out to Jotform Support. Unfortunately, our Spanish Support agents are busy helping other Jotform users at the moment. I'll try to help you in English using Google Translate, but you can reply in whichever language you feel comfortable using. Or, if you'd rather have support in Spanish, let us know and we can have them do that. But, keep in mind that you'd have to wait until they're available again.

Now, let me help you with your question. Are you referring to a pre-populated drop-down field that cannot be edited again? If so, yes, it is possible to do so. Let me walk you through it:

• In Form Builder, click on the Add Form Element menu on the left side of the page.
• Under the Widgets tab, search for the Get Form Page URL widget and add it to your form.

Now, let's set up the conditions:

1. In Form Builder, in the orange navigation bar at the top of the page, click on Settings.
2. Click on Conditions on the left of the page.
3. Now, click on Add a New Condition and then click on Enable/Require/Mask Field.

Set the conditions like you see below:

You can choose any of dropdown value. Check out this guide on Prepopulating Form Fields via URL Parameters. You can also use Prepopulate app. You can check out my clone form here.

Let us know if there's anything else we can help you with.
