Static dropdown have <select> tag while dynamic dropdown can have <nb-select>, <ng-select> or any other tag. Static dropdown with select tag can be easily handled using Cypress select command.

Dynamic dropdown could be auto suggestive or it can be a list as well. In this example we will handle Dynamic Dropdown List for ngx-admin application. Below is the screenshot for the dropdown in ngx-admin application

How to Handle Dropdown in Cypress

  it.only('verify dropdown', () =>{
    // Visit the homepage
   // Get the drodown
    cy.get("nav nb-select").then(dropdown =>{
      // Click on drodown
      // Iterate through each option, Here, index default value is 0
      cy.get("ul.option-list nb-option").each((listItem,index) =>{
        // ItemText to store Options value like Light, Dark, etc.
        const colorName = listItem.text().trim()
        //colorList will store color name and RGB value of each color in json format
        const colorsList = {
          "Light":"rgb(255, 255, 255)",
          "Dark":"rgb(34, 43, 69)",
          "Cosmic":"rgb(50, 50, 89)",
          "Corporate":"rgb(255, 255, 255)"
        // Click on each list item
        // Verify dropdown value after selection 
        // Verify color value after selection
        // Do not open dropdown for last selection
        if(index < 3)


In above example, we have used

const: Constants are block-scoped, much like variables declared using the let keyword. The value of a constant can't be changed through reassignment, and it can't be redeclared.
