Is it possible to disable the dropdown or radio list answer if that answer was selected in previous response.

Lets suppose a newly created survey has radio list Question as below

Question: Please select your time slot

A1 = 08:00 to 10:00
A2 = 10:00 to 12:00
A3 = 12:00 to 14:00

So in first response a user has selected A1 as per his availability then in next response A1 answer should not be visible to disabled

LimeSurvey is not offering answerrelevance fields, only subquestion relevance fields (which is multiplechoice). For your single choice drop down you will need to apply a workaround. If you only have a few items, you might create a question for every situation. If you have many items, there might be a solution via Javascript.
You should state what exact version of LimeSurvey you use. That is important to provide working workarounds.

Version 3.14.8+180829

Many thanks in advance

Hi,
what are you talking about?
Your topic is "dropdown", in your text you say

survey has radio list Question

For list(radio) you may use the workaround by inserting a (hidden) question of type multiple (M1), checking the respective subquestion by an (hidden) equation.
This question you use as array exclusion filter for your second list(radio).

If questions are on separate pages, you can use a hidden multiple-choice question to filter the second list-radio.

Search the forum - Joffm has given many examples of this.

Joffm... In my first thread i asked that if it is possible in dropdown or radio so I am ok with both as long as it is doable...

Can you please help me in more details as i dont know how to do above

The idea is to use a hidden multiplechoice question as filter for your second singlechoice question.

To define a question as a filter, take a look at
www.limesurvey.org/manual/Question_type_...r_.28array_filter.29

Perhaps you can find access to the idea via this thread:

Hi,
once again.






And remember, as Tony mentioned already: Both question on different pages.

Joffm

Joffm thanks for detailed reply but i just want to know if filter works with different responses such as my example above was with different responses

Yes,
Adapt the multiple question and the equation.

You will find everything to do that in the second link of jelo's reply.

Can you help me how can I do to filter by responses as I am still trying to figure this out
