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.

Use npm/yarn to install the package:

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

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

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);
}

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>

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>

Position fixed, breaking overflow:

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

Specific target:

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

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>

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

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

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

NgxFloatUiPopPlacements:

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!
