Component is standalone
This component does not require Bootstrap CSS to be used.
Colors of the component use the Bootstrap CSS vars (along with a default color) to ensure that if you do include bootstrap, the component will
take your color palette.
You will need to import the styles defined in @agnos-ui/core-bootstrap/css/tree.css or @agnos-ui/core-bootstrap/scss/tree.scss
These styles are also exported in the global export @agnos-ui/core-bootstrap/css/agnosui.css or @agnos-ui/core-bootstrap/scss/agnosui.scss
