ngx-float-ui

ngx-float-ui is an angular wrapper for the FloatingUI library (v ^1.5.3).

VERY IMPORTANT READ THIS

I'm moving this to the top because it appears that people don't get to reading it in the contribute section. FOR THIS LIBRARY PLEASE USE ISSUES ONLY FOR BUG REPORTING. DON'T OPEN ISSUES SUCH AS "I need upgrade for Angular 1745646456" especially if Angular 1745646456 was released a few days ago. I guarantee that I manage the updates AS SOON AS POSSIBLE. But as you understand this is not a paying job, so you can't get Angular 1745646456 the day it gets released. ISSUES NOT RESPECTING THIS WILL BE DELETED IMMEDIATELY WITHOUT ANY RESPONSE. Thank you.

Premise

The goal of this library is to adopt the more promising technology of floating-ui instead of popper.js and make it available in our Angular projects.

Installation

node and npm are required to run this package.

1. Use npm/yarn to install the package:

$ npm install @floating-ui/dom ngx-float-ui --save

Or

 $ yarn add @floating-ui/dom --save
 $ yarn add ngx-float-ui --save 

2. You simply add into your module NgxFloatUiModule:

import {NgxFloatUiModule} from 'ngx-float-ui';

@NgModule({
 // ...
 imports: [
   // ...
   NgxFloatUiModule
 ]
})

Optionally you can include in your styles.css / styles.css one of the prebuilt themes:

• @import node_modules/ngx-float-ui/css/theme-dark.css

• @import node_modules/css/theme-white.css

• @use ngx-float-ui/scss/theme as floatUiBaseTheme

• @use ngx-float-ui/scss/theme-dark as floatUiDarkTheme

• @use ngx-float-ui/scss/theme-white floatUiWhiteTheme

or easily create your own theme using the @mixin:

@use "ngx-float-ui/scss/theme" as floatUiBaseTheme;

body {
    @include floatUiBaseTheme.ngx-float-ui-theme($background-color, $text-color, $max-width, $z-index);
}

3. Add to view:

 <float-ui-content #popper1Content>
     <p class="bold">Popper on bottom</p>
 </float-ui-content>
 <div [floatUi]="popper1Content"
      [showOnStart]="true"
      [showTrigger]="'click'"
  	hideOnClickOutside
      [hideOnScroll]="true"
      [placement]="'bottom'">
     <p class="bold">Hey!</p>
     <p class="thin">Choose where to put your popper!</p>         
 </div>

4. As text:

     <div floatUi="As text"
          [showTrigger]="'hover'"
          [placement]="'bottom'"
          (onShown)="onShown($event)">
       <p class="bold">Pop</p>
       <p class="thin">on the bottom</p>
     </div>

     <div floatUi="{{someTextProperty}}"
          [showTrigger]="'hover'"
          [placement]="'bottom'"
          [styles]="{'background-color: 'blue''}"
          (onShown)="onShown($event)">
       <p class="bold">Pop</p>
       <p class="thin">on the bottom</p>
     </div>

5. Position fixed, breaking overflow:

     <div floatUi="As text"
          [showTrigger]="'hover'"
          [placement]="'bottom'"
          [positionFixed]="true"
          (onShown)="onShown($event)">
     </div>

6. Specific target:

<div class="example">
     <div #popperTargetElement></div>
     <div floatUi="As text"
          showTrigger="hover"
          placement="bottom"
          [targetElement]="popperTargetElement.nativeElement"
          (onShown)="onShown($event)">
     </div>

7. hide/show programmatically:

 <div [floatUi]="tooltipcontent"
      showTrigger="hover"
      placement="bottom"
      [applyClass]="'popperSpecialStyle'">
      <p class="bold">Pop</p>
      <p class="thin">on the bottom</p>
    </div>
    <float-ui-content #tooltipcontent>
      <div>
        <p>This is a tooltip with text</p>
        <span (click)="tooltipcontent.hide()">Close</span>
      </div>
    </float-ui-content>

8. Attributes map:

   | Option | Type | Default | Description | |:-------------------|:---------------- |:--------- |:---------------------------------------------------------------------------------------| | disableAnimation | boolean | false | Disable the default animation on show/hide | | disableStyle | boolean | false | Disable the default styling | | disabled | boolean | false | Disable the popper, ignore all events | | showDelay | number | 0 | Delay time until popper it shown | | hideTimeout | number | 0 | Set delay before the popper is hidden | | timeoutAfterShow | number | 0 | Set a time on which the popper will be hidden after it is shown | | placement | Placement(string) | auto | The placement to show the popper relative to the reference element * | | targetElement | HtmlElement | auto | Specify a different reference element other the the one hosting the directive | | boundaries | string(selector) | undefined | Specify a selector to serve as the boundaries of the element | | showOnStart | boolean | false | Popper default to show | | showTrigger | Trigger(string) | click | Trigger/Event on which to show/hide the popper | | positionFixed | boolean | false | Set the popper element to use position: fixed | | appendTo | string | undefined | append The popper-floatUi element to a given selector, if multiple will apply to first | | preventOverflow | boolean | undefined | Prevent the popper from being positioned outside the boundary * | | hideOnClickOutside | boolean | true | Popper will hide on a click outside | | hideOnScroll | boolean | false | Popper will hide on scroll | | hideOnMouseLeave | boolean | false | Popper will hide on mouse leave | | applyClass | string | undefined | list of comma separated class to apply on ngpx__container | | styles | Object | undefined | Apply the styles object, aligned with ngStyles | | applyArrowClass | string | undefined | list of comma separated class to apply on ngpx__arrow | | onShown | EventEmitter<> | $event | Event handler when popper is shown | | onHidden | EventEmitter<> | $event | Event handler when popper is hidden | | onUpdate | EventEmitter<> | $event | Event handler when popper is updated | | ariaDescribeBy | string | undefined | Define value for aria-describeby attribute | | ariaRole | string | popper | Define value for aria-role attribute |

* VERY IMPORTANT: All the "auto" placements can't be used in combo with prevent overflow (as per float-ui specs), because the two algorythms would conflict, ending in infinite repositioning. See here

9. Override defaults:

   ngx-float-ui comes with a few default properties you can override in default to effect all instances These are overridden by any child attributes.

NgModule({
    imports: [
        BrowserModule,
        FormsModule,
        NgxFloatUiModule.forRoot({placement: NgxFloatUiPlacements.TOP})],
    declarations: [AppComponent],
    providers: [],
    bootstrap: [AppComponent]

});

| Options | Type | Default | |:----------------------|:---------------------------------|:----------| | showDelay | number | 0 | | disableAnimation | boolean | false | | disableDefaultStyling | boolean | false | | placement | NgxFloatUiPopPlacements (string) | auto | | boundariesElement | string(selector) | undefined | | showTrigger | NgxFloatUiTriggers (string) | hover | | positionFixed | boolean | false | | hideOnClickOutside | boolean | true | | hideOnMouseLeave | boolean | false | | hideOnScroll | boolean | false | | applyClass | string | undefined | | styles | Object | undefined | | applyArrowClass | string | undefined | | ariaDescribeBy | string | undefined | | ariaRole | string | undefined | | appendTo | string | undefined | | preventOverflow | boolean | undefined |

10. NgxFloatUiPopPlacements:

| 'top' | 'bottom' | 'left' | 'right' | 'top-start' | 'bottom-start' | 'left-start' | 'right-start' | 'top-end' | 'bottom-end' | 'left-end' | 'right-end' | 'auto' | 'auto-start' | 'auto-end'

11. NgxFloatUiTriggers:

| 'click' | 'mousedown' | 'hover' | 'none'

Liking hardcoded strings everywhere? Too lazy to use Enums? No problem mate!

floatUiLoose is what you're looking for!

You can then use loosePlacement and looseTrigger passing the values above as strings!
