Hbuilder cannot call emmet

it is said that the tab key can call the function of emmet and expand the abbreviation of emmet. Why do I press the tab key and there is no response?

check whether the emmet plug-in tool > plug-in is installed before you can use it


first check whether the emmet plug-in is installed or disabled.
tools plug-ins

if it doesn't work, see if the keyboard shortcuts conflict with other software.
close other software and restart Hbuilder
