This is nice. If you are looking for more choices, Tabler[1] is another such component template, and I have used it to knock off visual dashboards fast. Not related; just another happy user.
Is this similar to those kitchen-sink bootstrap themes that used to be popular, with jquery, charting libs and whatnot included, that your client buys for you to speed things up even though you're coding React?
These things aren't analogous to React. They're more like opinionated and consistent design systems. This one is built on Tailwind.
Does anyone know if there is something like this based on tailwind or utilizing tailwind? All these frameworks seem to be based on bootstrap.
Flowbite and shadcn-ui are ones to look at. I also like rsuite but it's super bloated which is my main complaint, but it has the best check-tree-picker component I've found.
