Map Layer Labels as Hyperlinks (e.g., in PDF and QGIS2Web outputs)

[mtreg]

Feature description

First - huge thanks to all of the devs and supporters of QGIS, making it the great software that it is!

Second - here's the feature request: Desired End Result: Labels on a map, based on the data from a specified layer, are hyperlinks when the map is exported (from the Print Composer) as a PDF or interactive map (e.g., via QGIS2Web)

Why: In a variety of instances, with people interacting with maps on computers (or mobile devices), even as PDFs, the desired purpose of a label is not only to give the users the label information per se (e.g., the name of the administrative unit), but to serve as a link to some content on the web with more information. For example, for a map of administrative units, it can be useful to have the links to go more information specifically related to those units (e.g., a government website, specific thematic content, etc.)

Current experience:

• When creating labels based on the attribute table of a layer, users can select a field with HTML-formatted text, and the HTML formatting will apply for specific formatting related to visual styles documented here.
• Thus, if there is a column formatted to be hyperlinks (e.g., entries along the lines of <a href="https://qgis.org">QGIS</a>, the visual style makes the label appear as a hyperlink, but it does not function as one in any way that I have found.
• This holds true both when working in QGIS, and when exporting maps (e.g., from the Print Composer as a PDF using various different settings and PDF export drivers) nor in generating a webmap such as via QGIS2Web.
• For maps exported as PDFs from the Print Composer, the using the "Add Label" tool in the Print Composer with html-formatted hyperlinks and seems to function as one would expect, with the text that looks like a hyperlink functioning as one.

What I'm hoping to achieve is basically something like shown in the image below, where each of the labels, visually formatted as a standard HTML-formatted hyperlink (based on the attribute values and label setting checked for "Allow HTML formatted"), functions as a hyperlink, especially in a PDF but also, ideally, in interactive maps such as those generated through QGIS2Web

Hi ! I have been searching for creating these labels hyperlinks, but also with no success.

Is there a way to solve this? Maybe using phyton?
