TPAC 2024 WHATUP meeting agenda

The WHATWG (Web Hypertext Application Technology Working Group) community will meet at the Technical Plenary (TPAC) 2024 in Anaheim, CA USA the week of 23 September 2024. We call this the "Web HyperText Application Technology Unconference Plenary" or WHATUP for short. See the overall meeting page for conference, hotel, and travel logistics. Registration is required.

Remote participation is available via Zoom. People who can are encouraged to attend as the face to face opportunity is valuable for the work, but W3C expects many people to be unable to attend and plans to provide quality remote participation support. Note that registration is required for remote participants.

The purpose of this meeting is to make progress on the current open tasks in a high-bandwidth medium that an in-person meeting provides. Additionally it will be an excellent opportunity to strengthen the relationships between all participants by spending some time together after a long time. There is a draft agenda below, but it will become more concrete closer to TPAC, when it becomes clear what issues have been resolved and what new topics have come up.

Please suggest topics in the comments below and I will incorporate them in the agenda.

"tooltips"

I'd like to actually expand this to "tooltips, hover-menus, and other hover-triggered popovers". Same links work.

[past]

Got it, updated.

[sanketj]

@past We'd like to discuss the following topics at TPAC. Would you be able to add them to the agenda?

Joint session with OpenUI & CSS WG: openui/open-ui#1088 cc: @alexkeng
WHATWG session: whatwg/html#10614 cc: @siliu1

[past]

Sure thing, done.

[keithamus]

@past I'd love to get openui/open-ui#1090 on the agenda with the joint OpenUI & CSSWG task force. This is a proposal document on expanding input & textarea elements to include richer styling & interactivity.

[jeremyroman]

I'd like the opportunity to mention companion windows during the WHATWG solo session (tentative explainer, should be slightly better formatted as a GitHub repository by next week) so that folks who are interested can share brief comments and follow up with us afterward.

[past]

Added both of these. Jeremy, let me know when the explainer repo is up so that I can link to it.

[yoavweiss]

Can we add scheduling API updates to the WebPerfWG joint session?
