But why is it a radio button, instead of a checkbox? Snif.

html 4 ever 🙌

html also has check boxes

Thanks, I know, sorry for being vague! 🙏😅 I just got excited to see the word "radio button" being used and got nostalgic AF. 🤣

Checkbox implies that multiple options can be picked, radial button entails only one can be chosen. The latter could be appropriate for the question.

Bigender, agender, pangender, genderfluid

I had a man tell me the other day: "I don't know if you're a boy or a girl!"

and I just replied "me neither!"

Multiple, not listed. If the question of gender is part of a larger set of questions and not the focus the people that will be looking at the data might want simpler, easy to read data for that portion in which case having only one answer for the question per participant would be preferable. Of course we don’t know what the actual case is based on a meme, which is why I wrote “could be” appropriate instead of “is the only” appropriate option.

The joke in my question is that I actually match all three options at the same time. (The joy of being trigender man + women + undetermined_NB.)

the data might want simpler, easy to read data

You can get that from the information. Its possible to split the results into whether someome selected one or multiple options

Of course, a comprehensive gender survey needs at least 15 more sliders

Slider?

True, forgot this one.
To combine, a multi-dimensional slider ? (Beacause while being a spectrum, gender isn't a single axis defined by two discreet points.

By the way, although being a IT techie, I didn't even intend to make it a tech joke. That's just professionnal deformation I didn't even notice before reading the first comment.

I rarely even directly touch HTML code. (My devs are more middleware oriented, even though they are related to web apps and services.)

Ooh like a colour picker, that triangle/wheel thingy. Probably still not enough dimensions but at least colourful

Yup, that's the idea.

No worries! I haven't touched HTML since... junior high? 🤣 I'm learning C now. 😁
