Popover (tooltips, dropdowns, etc)

Our popover components wrap an external library called tippy.js. We recommend going through their documentation if you have trouble using them.

My tooltip does not show up on hover.

This can happen if the child component does not forward its ref (see docs). It can also happen if the child component is disabled. One workaround is to wrap your content in a div or span.

My tooltip appears cut off!

This can happen due to the parent container using CSS overflow or position: absolute or z-index stacking contexts. (By default, Tooltip is appended to the parent container.) The workaround is to use appendTo={() => document.body}.

Table

Our table is a styled wrapper around react-table. We recommend going through their documentation and issues before opening new issues in iTwinUI-react.

Missing table features

If you find that the table is missing a feature, there may already be an existing issue for it. You can upvote 👍 the relevant issue (and/or leave a comment) to help us prioritize it.

• Resizable columns
• Virtualized rows
• Pagination
• Expandable sub-rows

Conflicts with react-table v6

iTwinUI-react uses react-table v7, which can cause problems if your project is also using react-table v6. Using custom aliases in package.json for both react-table v6 and its types can help:

...
"react-table-v6": "npm:react-table@^6.11.5"
...
"@types/react-table-v6: "npm:@types/react-table@^6.8.8"
