Installation

Install the npm package.

npm i ng2-tooltip-directive

Import Ng2Module:

``ts
import { TooltipModule } from 'ng2-tooltip-directive';

@NgModule({
imports: [ TooltipModule ]
})
`

Usage

Options can be set in the directive tag, so they have the highest priority.

`html
Tooltip on top
`

You may pass as an object:

`html
Tooltip on left
`
`ts
myOptions = {
'placement': 'left',
'showDelay': 500
}
`

You can pass HTML as content :

`html

Tooltip with HTML content

`

`html

Hello i'm a bold text!

Tooltip with template content

`

Set default values

Create a file with your settings, for example:
`ts
import { TooltipOptions } from 'ng2-tooltip-directive';

export const MyDefaultTooltipOptions: TooltipOptions = {
'show-delay': 500
}
`

And pass your parameters when importing the module:
`ts
import { TooltipModule, TooltipOptions } from 'ng2-tooltip-directive';
import { MyDefaultTooltipOptions } from './my-default-options';

@NgModule({
imports: [
TooltipModule.forRoot(MyDefaultTooltipOptions as TooltipOptions)
]
})
``
