Topic: Display the dropdown menu upwards

Frederic priority asked 4 years ago


Hello, The following list has a dropdown menu opening for each line.

It displays all the options, ...

enter image description here

... but, the options are not displayed if its height is longer than the table (see screenshot on the screen)

enter image description here

Is it possible to display the dropdown menu upwards if the menu is too long and hides below the table?

Here’s an example of the code:



import { Component, OnInit, ViewChild } from '@angular/core';
import { ModalDirective } from 'ng-uikit-pro-standard';

@Component({
  selector: 'app-list-test',
  templateUrl: './list-test.component.html',
  styleUrls: ['./list-test.component.css']
})
export class ListTestComponent implements OnInit {
  @ViewChild('formTestModal', { static: true }) formListTestModal: ModalDirective;

  public headers: Array = new Array("Name", "Surname", "Country", "City", "Position", "Age");
  public listInfo: Array = new Array();

  constructor() {
    this.listInfo = [
      { id: 1, check: false, name: "Kate", surname: "Moss", country: "USA", city: "New York City", position: "Web Designer", age: 23 },
      { id: 2, check: false, name: "Anna", surname: "Wintour", country: "United Kingdom", city: "London", position: "Frontend Developer", age: 36 },
      { id: 3, check: false, name: "Tom", surname: "Bond", country: "Spain", city: "Madrid", position: "Photographer", age: 25 },
      { id: 4, check: false, name: "Jerry", surname: "Horwitz", country: "Italy", city: "Bari", position: "Editor-in-chief", age: 41 },
      { id: 5, check: false, name: "Janis", surname: "Joplin", country: "Poland", city: "Warsaw", position: "Video Maker", age: 39 },
      { id: 6, check: false, name: "Gary", surname: "Winogrand", country: "Germany", city: "Berlin", position: "Photographer", age: 37 },
      { id: 7, check: false, name: "Angie", surname: "Smith", country: "USA", city: "San Francisco", position: "Teacher", age: 52 },
      { id: 8, check: false, name: "John", surname: "Mattis", country: "France", city: "Paris", position: "Actor", age: 28 },
      { id: 9, check: false, name: "Otto", surname: "Morris", country: "Germany", city: "Munich", position: "Singer", age: 35 },
      { id: 10, check: false, name: "Kate junior", surname: "Moss", country: "USA", city: "New York City", position: "Web Designer", age: 13 },
      { id: 11, check: false, name: "Anna junior", surname: "Wintour", country: "United Kingdom", city: "London", position: "Frontend Developer", age: 26 },
      { id: 12, check: false, name: "Tom junior", surname: "Bond", country: "Spain", city: "Madrid", position: "Photographer", age: 15 },
      { id: 13, check: false, name: "Jerry junior", surname: "Horwitz", country: "Italy", city: "Bari", position: "Editor-in-chief", age: 31 },
      { id: 14, check: false, name: "Janis junior", surname: "Joplin", country: "Poland", city: "Warsaw", position: "Video Maker", age: 29 },
      { id: 15, check: false, name: "Gary junior", surname: "Winogrand", country: "Germany", city: "Berlin", position: "Photographer", age: 27 },
      { id: 16, check: false, name: "Angie junior", surname: "Smith", country: "USA", city: "San Francisco", position: "Teacher", age: 42 },
      { id: 17, check: false, name: "John junior", surname: "Mattis", country: "France", city: "Paris", position: "Actor", age: 18 }
    ];

Hi @Frederic,

Please use [dynamicPosition]="true" property in your code. More about it you can find here.

Please add this like this:

<div class="dropdown btn-group" mdbDropdown [dynamicPosition]="true">

Please check it and tell if you still have a problem.

Best, Konrad.

Hello,

I've tried to add [dynamicPosition]="true" but it doesn't work.

<div class="dropdown btn-group" mdbDropdown [dynamicPosition]="true">

I've also tried [dropup]="true", but it doesn't work either.

<div class="dropdown btn-group" mdbDropdown [dropup]="true">

Any ideas?


Konrad Stępień staff commented 4 years ago

We don't have for this time a feature for change position of the dropdown on scroll event, but I can add this suggestion for our todo list.

dynamicPosition working only for opening select when the component doesn't have space for showing the menu.
