This can't be right.
For instance, if a character uses an action (or a bonus cunning action) to make a DEX check to hide, and then starts beating on his/her shield with his/her sword, s/he doesn't remain silent. Hence s/he doesn't remain hidden (SRD p 80: "you give away your position if you make noise").
It is right. I said in my post here that unless you come out of hiding in some manner, you are hidden with a single roll and there is no need for ongoing "attempts to hide". Beating on your shield is taking an action to stop hiding. No rule supports [MENTION=6787503]Hriston[/MENTION]'s claim.
As I understand it, this is the point that @Hriston is making - that to remain hidden, you have to maintain the conditions that ensure your position isn't given away (eg you must refrain from deliberately making noise, you must remain from deliberately providing visual cues, etc - the DEX roll tells us whether or not you inadvertantly make noise or provide visual cues).
Not making noise =/= needing to try not to make noise. RAW allows you to remain X silent, where X is your stealth roll to hide. There is no need to try any further not to make noise, because that lack of noise to the extent of your roll is automatic and constant for the duration of the hide. For instance, if my hide check is 15, I am at a 15 for lack of visual and audible clues for the entire time I am hidden. RAW doesn't require me to make any further efforts to remain silent or out of sight. You can assume that there is some sort of constant hide check going on, but that only applies to your personal game, not the rules.
As I understand it, the point of the elf or halfling abilities is not that they can be simultaneously hidden and noticed (which would be an absurd contradiction) but that they can be hidden in conditions where most people would be noticed. When Sage Advice says
The lightfoot halfling and wood elf traits—Naturally Stealthy and Mask of the Wild—do allow members of those subraces to try to hide in their special circumstances even when observers are nearby. Normally, you can’t hide from someone if you’re in full view. A lightfoot halfling, though, can try to vanish behind a creature that is at least one size larger, and a wood elf can try to hide simply by being in heavy rain, mist, falling snow, foliage, or similar natural phenomena. It’s as if nature itself cloaks a wood elf from prying eyes
it seems fairly clear to me: normally you can't hide if you're in full view (invisibility, or some forms of distraction, might generate exceptions to this general proposition), but an elf in a mist or snowfall is not in full view. Rather, nature itself cloaks the elf. As long as the snow continues, the elf will continue to be cloaked, and hence will remain hidden (as long as s/he doesn't deliberately make noise or provide visual cues, and as long as the DEX check is successful and hence s/he doesn't inadvertently make noise or provide visual cues).
The elf IS in full view, at least until he uses nature to cloak himself and go out of view. The sage advice says straight out that the elf can do so while being stared at directly. The elf is hiding while being observed.
I would think it is obvious that, in so far as the elf remains cloaked and hence hidden, s/he is not being observed. People might be looking - even staring - in his/her direction, but if nature is cloaking the elf and the elf is neither deliberately nor inadvertently providing visual cues then s/he is not being observed. Hidden is basically synonymous with concealed from sight!
It does't say staring in the elf's direction. It says the elf can try to hide while someone is staring at the elf. That's the ability to hide while under observation. In any case, even partial view has the elf still being directly observed.
