Vue js Disable selected dropdown options
Vue js Disable selected dropdown options:To disable selected dropdown options in Vue.js, you can use the :disabled
attribute binding along with a conditional statement. First, bind the disabled
attribute to a Boolean variable in your data object, for example, isOptionDisabled
. Then, in your dropdown options, use the v-bind
directive to conditionally apply the disabled
attribute based on the value of isOptionDisabled
. This can be achieved using a computed property or a method that checks the selected value against the values you want to disable. Finally, update the isOptionDisabled
variable whenever the selected value changes to dynamically enable or disable the options.

How can selected options in a dropdown menu be disabled using Vue.js?
In the given Vue.js code, the dropdown options are dynamically disabled based on the selected value. The v-model
directive is used to bind the selected value to the selectedValue
variable in the Vue app's data. Each <option>
element in the dropdown is generated using v-for
directive, iterating over the options
array.
The :disabled
attribute is conditionally set to true
if the selectedValue
is equal to the current option's value. This disables the option, making it unselectable. The selected value is displayed below the dropdown using {{ selectedValue }}
in the <p>
tag.

How can I disable multiple selected options in a dropdown menu using Vue.js?
This Vue.js code snippet demonstrates how to disable multiple selected options in a dropdown menu. The <select>
element has the multiple
attribute to allow multiple selections. Inside the <select>
, an <option>
element is generated for each item in the options
array using v-for
.
The v-bind:value
directive binds the option.value
to the selected value. The :disabled
attribute is used to disable options if their values are included in the selected
array. The selected
array contains the initially selected values. As a result, the dropdown will have options 'One', 'Two', 'Three', and 'Six' disabled because they are already selected.
To select multiple options in a dropdown, hold down the Shift key and click on the desired options.
