HTMLSelectElement: size property
The size property of the HTMLSelectElement interface specifies the number of options, or rows, that should be visible at one time. It reflects the <select> element's size attribute. If omitted, the value is 0.
Note:
While by default a <select> displays a single row unless multiple is true, in which case four rows are displayed, the default value for the size property is 0.
Value
A number.
Examples
js
const selectElement = document.getElementById("fruits");
console.log(selectElement.size);
