Time limit for REQUIRED survey items

[silviaformica]

Hi all,
I am trying to design a survey that has three questions for each trial. I am using the plugin-survey-likert, and I set all three questions as REQUIRED to allow participant to submit. Everything works nicely so far.
However, I would like to also include a time limit, so that, if after this trial_duration has passed the participant has not yet submit the answers, the survey continues to the next trial.

I have been trying to modify the plugin to include this trial_duration. I added trial_duration as a trial attribute:

          /** How long to show trial before it ends */
          trial_duration: {
             type: jspsych.ParameterType.INT,
             pretty_name: "Trial duration",
             default: null,
          },

I tried to use the suggestions in this ( #2995) and other discussions, so I added this code:

        // end trial if trial_duration is set
          if (trial.trial_duration !== null) {
            jsPsych.pluginAPI.setTimeout(function () {
            // when the time limit is up, automatically submit the form and end the trial
            display_element.querySelector('#jspsych-survey-likert-form').requestSubmit();
            }, trial.trial_duration);
          }

This works only partially: after the trial_duration has expired, the plugin simulates the form submission, but this is halted because the response to the questions is set as required. Therefore, after trial_duration has expired, the only effect I obtain is to trigger the appearance of the "please select one of these options" message.

How can I override the REQUIRED attribute after the trial_duration has expired?

So far, I tried to manually modify the options_strings of the trial, and to make a custom-made end_trial function, but with no success.
Thanks a lot for any help!

Update in case someone will stumble upon a similar problem in the future.
I figured out a way that works for me, adding the following lines:

        // end trial if trial_duration is set
          if (trial.trial_duration !== null) {
            jsPsych.pluginAPI.setTimeout(function () {

            // Select all input elements inside the form
            const inputs = document.querySelectorAll('form input');

            console.log(inputs)

            // Loop through each input and remove the 'required' attribute
            inputs.forEach(input => input.removeAttribute('required'));

            // when the time limit is up, automatically submit the form and end the trial
            display_element.querySelector('#jspsych-survey-likert-form').requestSubmit();
            }, trial.trial_duration);
          }
