This package contains all Vaadin web components (free and commercial).
See https://github.com/vaadin/web-components for more details.
Our current interfaces to connect data (lazily) to components such as Grid and ComboBox have shortcomings that make it difficult or impossible to use in certain situations, such as when the backend only allows paged access or when calculating the size of resultset is slow or not supported at all.
Commenting / Activity log experience
Team communication capabilities like TaskMob can be added to your app with off the shelf components
The dropdown does not work on Vite
Please see example repo below. The code is in the HelloWorld Vue component.
just clone, install and run dev
I'm not using any of the Vaadin Pro web components, but I keep seeing the message over my application that I need to go get the license.
Here is the piece of code which lists all of the components I am using:
Promise.all([
customElements.whenDefined("vaadin-list-box"),
customElements.whenDefined("vaadin-item"),
customElements.whenDefined("vaadin-button"),
customElements.whenDefined("vaadin-grid")
])
And I import them individually.
I do not use grid pro, only grid.
What should I do?
It would be great to get an overview of the status which components have been (re-)developed already based on lit-html and lit-element on this page: https://github.com/vaadin/vaadin
Thanks.
Similarly to vaadin-core/vaadin-core.html
import, we should have a vaadin/vaadin.html
import which imports all the components in the package.
Hi,
I am using a Vaadin controls in our application (lit-element and polymer). I saw the styles of vaadin component are rendered in head tag under "dom-module". I am want to confirm that why these styles are rendered in head tag rather than being the part of shadow-dom.
Also, when a route is changed and vaadin components are removed from dom then these styles are still there in head tag.
Is there a way to render these styles as a part of shadow dom rather than head tag.
Please suggest us.
Thanks.
Support RTL in all components and switch between LTR and RTL with one line of Java code.
Hi,
We are trying to create Angular wrapper for Vaadin WebComponents using Angular directives.
Why we are doing this?
What we did ?
import { Component, NgZone } from '@angular/core';
import {CheckboxElement} from '@vaadin/vaadin-checkbox/src/vaadin-checkbox.js'
import { ChangeDetectorRef, ElementRef } from '@angular/core';
import '@vaadin/vaadin-checkbox';
@Component({
selector: 'vaadin-checkbox',
template: '<ng-content></ng-content>',
})
export class CheckboxComponent extends CheckboxElement {
protected el: HTMLElement;
constructor(c: ChangeDetectorRef, r: ElementRef, protected z: NgZone) {
super(c, r, z); // Here we tried super(); also
c.detach();
this.el = r.nativeElement;
}
}
<vaadin-checkbox >Ok</vaadin-checkbox>
core.js:5809 ERROR TypeError: Illegal constructor
at new PropertiesChanged (properties-changed.js:166)
at new PropertyAccessors (property-accessors.js:115)
at new TemplateStamp (template-stamp.js:171)
at new PropertyEffects (property-effects.js:1107)
at new PropertiesMixin (properties-mixin.js:113)

at new VaadinThemableMixin (vaadin-themable-mixin.js:8)
at new VaadinTabIndexMixin (vaadin-control-state-mixin.js:11)
We tried passing super() and with arguments but still getting this illegal constructor.
Could you please suggest how we can extend Vaadin control at Angular side?

Basanth
Hi
Maybe you want to register the namespace "vaadin" here with a pull request?

Adds a new column type that makes the cells on that column editable inline. (Double)clicking a cells turns the cell content into an editor component that gets its value from the row item's sub-property defined by the columns path
.
Closing the editor will make grid emit an event specific to this feature so that application logic can make necessary changes to the data.
Navigating between the cells of editable columns (while editing) can be done by (shift) tabbing.
From time to time, users are asking us about free and pro parts of our offering.
Question: vaadin/vaadin-login#50 (comment)
How are make-it-free decisions made? Are there specific criteria for a component to meet, or random chance during team discussion, or...
Answer: vaadin/vaadin-login#50 (comment)
It is more of a case-by-case matter (... and some details about the specific case)
This is probably not what the users actually expect. It would be nice to have a clear strategy documented on the website and linked from each of the PRO component repositories.
It would be extremely nice to get an IDE auto complete supported for the packaged web components on the npm repo. When I import the @vaadin/vaadin
, I don't get any support at least in VS Code. Such things as showing the properties inside of the @vaadin/vaadin-progress-bar
would be fantastic so I didn't have to go check the docs every time.
Sorry if this isn't the right place, feel free to point me elsewhere!
