  <!-- Select Dropdown -->
  <label for="selectOption">Choose an option:</label>
  <select class="form-select" id="selectOption" name="option" aria-label="Default select example">

</form>

Explanation:

1. Form Element: The <form> tag wraps around the input elements (<input> and <select>) and the submit button (<button type="submit">Submit</button>).

2. Input with Datalist:

   • <input>: This is where users can type to search for options.

   • list="datalistOptions": Associates the <input> with the <datalist> element by referencing its id.

   • autocomplete="off": Disables browser autocomplete for this input field.

   • <datalist>: Contains the options that users can choose from when typing in the <input> field.

3. Select Dropdown:

   • <select>: Provides a dropdown menu with selectable options.

   • class="form-select": Bootstrap class for styling purposes.

   • aria-label="Default select example": Provides an accessible label for screen readers.

   • <option>: Defines the selectable options within the dropdown. The selected attribute marks the default selected option.

4. Submit Button:

   • <button type="submit">Submit</button>: When clicked, this button submits the form to the server specified in the action attribute of the <form> tag.

5. Attributes and Labels:

   • for="datalistInput" and for="selectOption": Associates labels with their respective form elements for accessibility.

   • name="city" and name="option": Specifies the names of the form fields that will be submitted with their respective values.

This structure ensures that users can choose options either by typing in the <input> field with autocomplete suggestions from the <datalist>, or by selecting an option from the <select> dropdown menu. Adjust the action attribute in the <form> tag to the appropriate server endpoint where you want to handle the form submission data.
