Product

Device & OS

Scenario
Creating educational worksheets or assignments in PDF format that require students to perform both form filling and text highlighting activities.
Observed behavior
Creators are unsure how to enable highlighting within a form, as highlighting is a commenting feature rather than a dedicated form-field function.
Before you start

Understand that text highlighting is a standard PDF commenting feature, whereas form fields are interactive input elements. You do not need to create a specific form field to allow text highlighting.

Solution 1Recommended

Create the Source Document and Add Form Fields

Design the static text of your assignment in a word processor, export it to PDF, and then add interactive form fields.

Text highlighting is a standard PDF commenting element supported by nearly all PDF viewers. It is entirely separate from form filling.

To build an effective assignment, you should design the readable text in a standard authoring application and only use PDF software to add the interactive form fields.

1
Create the base document

Open a word processor like WPS Writer or Microsoft Word to type out the lesson instructions, reading materials, and questions.

2
Export to PDF

Navigate to 'File' and select 'Export to PDF' or 'Save as PDF' to convert your text document into a static PDF file.

3
Insert fillable fields

Open the exported PDF in a dedicated PDF editor, navigate to the 'Form' tab, and insert text boxes, checkboxes, or dropdowns where student input is required.

4
Save and distribute

Save the final interactive PDF document and distribute it to your students for their assignments.

Device Compatibility: Many students use smartphones and tablets. Test your final PDF workflow on mobile devices to ensure both form filling and commenting tools work smoothly.

Frequently Asked Questions

Is highlighting text the same as filling out a PDF form?

No, highlighting is a commenting activity that overlays color on existing text. Filling out a form involves entering new data into pre-defined interactive fields. They are separate actions but can be done on the same document.

Do I need to create a specific form field to allow highlighting?

No. You do not need to add any special form fields for highlighting. Highlighting relies entirely on the PDF reader's built-in commenting tools, which are universally supported by standard PDF viewers.

Will students' highlights show up when they submit the PDF?

Yes, as long as the student saves the PDF document after making their highlights. The highlights are saved as standard PDF annotations and will be visible when you open their submitted file.

Can students highlight text on mobile phones or tablets?

Yes, most mobile PDF reader applications support text highlighting. However, interfaces vary between apps, so it is highly recommended to test the workflow on mobile devices and provide your students with app-specific instructions.
