How to open the desktop popup on mobile devices using the Syncfusion JavaScript ComboBox component?

This article provides a solution for customizing the behavior of the JavaScript ComboBox popup on mobile devices to resemble desktop interaction. It covers adjusting parameters on event handlers to achieve the desired effect.

Implementation

To achieve this, set the window.browserDetails.isDevice parameter to false within the beforeOpen event. This adjustment ensures that the ComboBox popup opens in a desktop manner on mobile devices.

  beforeOpen: (args) => {
    (window as any).browserDetails.isDevice = false;
  }

Additionally, revert the window.browserDetails.isDevice parameter to true within the close event. This ensures that the popup maintains its visibility as a desktop-style popup exclusively during its opening. By implementing this approach, you ensure seamless functionality and deliver a better user experience.

  close: (args) => {
    (window as any).browserDetails.isDevice = true;
  },

Please find the combobox code snippet below:

let comboBoxObj: ComboBox = new ComboBox({
  placeholder: 'Select a game',
  beforeOpen: (args) => {
    (window as any).browserDetails.isDevice = false;
  },
  close: (args) => {
    (window as any).browserDetails.isDevice = true;
  },
});
comboBoxObj.appendTo('#games');
