Note: I am not the author of this project, see their [official repository].(https://github.com/drozhzhin-n-e/ng2-tooltip-directive). The author doesn't seem to maintain its project anymore, so I'm just fixing stuff to update to new angular versions.

Tooltip for Angular


The tooltip is a pop-up tip that appears when you hover over an item or click on it.

Supported Angular versions

This version of the library support Angular version 15 and up.

Installation

Install the npm package.

npm i ng2-tooltip-directive-major-angular-updates

Import NgModule:

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

@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-major-angular-updates";

export const MyDefaultTooltipOptions: TooltipOptions = {
"show-delay": 500,
};
`

And pass your parameters when importing the module:

`ts
import { TooltipModule, TooltipOptions } from 'ng2-tooltip-directive-major-angular-updates';
import { MyDefaultTooltipOptions } from './my-default-options';

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