hello – the documentation says:
delay number
Gets or sets whether a tooltip’s arrow will be shown. (this was meant for the arrow property)
Default value 0
Example
Set the delay property.
<smart-tooltip delay='true'></smart-tooltip>
i believe it should look like this:
delay number
Gets or sets the tooltip delay in milliseconds.
Default value 0
Example
Set the delay property for two seconds.
<smart-tooltip delay=2000></smart-tooltip>
