  <div class="" mdbCollapse [isCollapsed]="collapsed">
      <div class="col-sm-12 col-md-auto">
        <div class="md-form mb-0">
          <input type="text" class="form-control" name="search" [(ngModel)]=""
                id="search" mdbInput>
          <label for="search">{{'Search' | translate}}</label>


filterBtn() {
if (this.collapsed === true) {
  this.collapsed = false;
  console.log('Set to false');
  // other my code
} else {
  this.collapsed = true;
  console.log('Set to true');
  // other my code


But collapse does'nt works :( What's wrong ?

In this case please use toggle method of the Collapse component.

<div class="" mdbCollapse [isCollapsed]="collapsed" #collapse="bs-collapse">
  <div class="col-sm-12 col-md-auto">
    <div class="md-form mb-0">
      <label for="search">Search</label>

If you need access to the component methods in your ts file:

  @ViewChild('collapse') collapse: CollapseComponent;
  collapsed = false;

  filterBtn() {
    if (this.collapsed) {;
      this.collapsed = false;
    } else {
      this.collapsed = true;

Hi Arkadiusz, i saw that need also import { CollapseComponent } from 'ng-uikit-pro-standard';

and filterBtn() is never fired.. whats wrong ?

Arkadiusz Idzikowski staff commented 2 years ago

The code snippets I provided are for two completely different approaches to toggle the collapse or use its other public methods. The first example should work out of the box when you copy the code to your component HTML file. It uses #collapse="bs-collapse" to get access to the collapse method in the template.

The second example is useful when you need to have access to the collapse methods in the ts file. In this case, you need to import the CollapseComponent and attach the filterBtn method to the button click handler.

If possible I would need more help.. This is my html code: html

Now toggle works fine but my filter are slitted on second row: filter OFF filter ON

But i'd like to have all in one row, right to filterBtn: filter in on row

How can do this ?
