Please prioritize this and add this to your roadmap as soon as possible.

Yes, please.

Need this urgent!

5 year i'm waiting a target=_blank on the hyperlink-url ......................

This seems like a basic and essential feature. Please consider prioritizing it!

I'm trying to implement a voting system for a magazine ... People should be able to vote an article in a magazine up, down or neutral ... the whole system works perfectly when the interactive pdf is open in acrobat but when it opens in a browser, readers loose their position in the magazine and have to go back (in the browser) and then search where they were before and read on ... these users only ever vote for one article ... and then never again ...
Please implement this feature ... this would solve this whole problem for me ...

Please create an option to have hyperlinks open in a new tab and/or window. The ability to determine HOW a hyperlink opens is just as important as the link itself. This feature is vital for many of the projects I design. Please add this!

This is a simple ask but will be extremely effective

Please priortise this as an accessibility improvement, thank you.

This is surely a must need for everyone. To be able to edit the HTML that is generated for each hyperlink, so that designers could customize it to include target="_blank".

It would be great if the developers could edit the InDesign Hyperlinks palette to include some kind of access to edit the HTML that is generated for each hyperlink, so that designers could customize it to include target="_blank". Perhaps it's a simple radio button that gets clicked to automatically add that command to any selected hyperlink's HTML behind the scenes. However it might be done, it would be very helpful to those of us who are publishing PDFs that folks access online and then happen to open inside of their web browser instead of downloading to their desktop. In this scenario, since they are viewing the PDF in their browser, when they click on an external link in the PDF, the view of the PDF is replaced by whatever link they clicked on, and they would have to use their browser's back button to get back to the PDF. Not ideal.

Why isn't this a thing?! This is basic stuff, surely!

Critical feature that is needed

We need the option to open in a new tab as well.

This post is getting more attention, btw: https://indesign.uservoice.com/forums/601021-adobe-indesign-feature-requests/suggestions/37223290-open-hyperlinks-in-new-tab

Please, please, please add this basic functionality.

This is critical for our work as well. We create patient guides where users need to be able to open a hyperlink to important additional information WITHOUT losing their place in the guide online!!!

I have been researching the same thing for hours now and I'm on Adobe Help Chat but not looking good.

To me, the ability to determine HOW a hyperlink opens is just as important as the link itself. The fact that code that's been used as an <A> tag modifier since HTML 3 is still not available is amazing to me when I see all the pointless features I never use in InDesign being added. Acrobat has the ability to read it since it's the only current way to set a Target="_blank" to get a new window at the current time. If Acrobat can read it, InDesign should be able to insert in and keep it with the hyperlink library for future updates. This isn't a bug, to me this is a broken feature.

Here's an additional place to insert your comments and suggestions, since this one doesn't seem to be getting much traction.
