Hi to everyone, This is my first post here, I have 4 location select boxes with options like full chest, full back, front left chest, front right chest and so on and 4 color boxes that say the number of colors. I am showing location one and color one select box as default, and increment them by using add one more location button or removing them by using remove location button. I am also resetting the select box of a particular location and its color, if that location is removed. Also If one option is selected in one of the select boxes that option should be disabled in the remaining 3 select boxes. ( I have this part working ) Now, If full chest is selected in any one of the select boxes then front left chest and front right chest should be disabled in the remaining 3 select boxes. ( this part not working ) Also When I remove a location and resetting that location value, I am having hard time re-enabling the disabled option from other location boxes or the default location. Here is a JSFIDDLE ( https://jsfiddle.net/booq3ota/ ) Here is my HTML CODE and CSS: <div class="pc-row location-1"> <div class="locations-colors pc-col quote-sizes"> <h4>Choose location below</h4> <label for="location_one"><span>Location</span> <select name="location_one" id="location_one" class="linked-drop-down"> <option value="">choose location</option> <option value="Full_Chest">Full Chest</option> <option value="Full_Back">Full Back</option> <option value="Front_Left_Chest">Front Left Chest</option> <option value="Front_Right_Chest">Front Right Chest</option> <option value="Left_Sleeve">Left Sleeve</option> <option value="Right_Sleeve">Right Sleeve</option> </select></label> </div> <div class="locations-colors pc-col quote-sizes"> <h4>Choose number of colors for location</h4> <label for="color_one"><span>Number of Colors</span> <select name="color_one" id="color_one"> <option value="">choose colors</option> <option value="0">One Color</option> <option value="1">Two Colors</option> <option value="2">Three Colors</option> <option value="3">Four Colors</option> </select></label> </div> </div> <div class="pc-row location-2"> <div class="locations-colors pc-col quote-sizes"> <label for="location_two"><span>Location</span> <select name="location_two" id="location_two" class="linked-drop-down"> <option value="">choose location</option> <option value="Full_Chest">Full Chest</option> <option value="Full_Back">Full Back</option> <option value="Front_Left_Chest">Front Left Chest</option> <option value="Front_Right_Chest">Front Right Chest</option> <option value="Left_Sleeve">Left Sleeve</option> <option value="Right_Sleeve">Right Sleeve</option> </select></label> </div> <div class="locations-colors pc-col quote-sizes"> <label for="color_two"><span>Number of Colors</span> <select name="color_two" id="color_two"> <option value="">choose colors</option> <option value="1">One Color</option> <option value="2">Two Colors</option> <option value="3">Three Colors</option> <option value="4">Four Colors</option> </select></label> </div> </div> <div class="pc-row location-3"> <div class="locations-colors pc-col quote-sizes"> <label for="location_three"><span>Location</span> <select name="location_three" id="location_three" class="linked-drop-down"> <option value="">choose location</option> <option value="Full_Chest">Full Chest</option> <option value="Full_Back">Full Back</option> <option value="Front_Left_Chest">Front Left Chest</option> <option value="Front_Right_Chest">Front Right Chest</option> <option value="Left_Sleeve">Left Sleeve</option> <option value="Right_Sleeve">Right Sleeve</option> </select></label> </div> <div class="locations-colors pc-col quote-sizes"> <label for="color_three"><span>Number of Colors</span> <select name="color_three" id="color_three"> <option value="">choose colors</option> <option value="1">One Color</option> <option value="2">Two Colors</option> <option value="3">Three Colors</option> <option value="4">Four Colors</option> </select></label> </div> </div> <div class="pc-row location-4"> <div class="locations-colors pc-col quote-sizes"> <label for="locatio_four"><span>Location</span> <select name="location_four" id="location_four" class="linked-drop-down"> <option value="">choose location</option> <option value="Full_Chest">Full Chest</option> <option value="Full_Back">Full Back</option> <option value="Front_Left_Chest">Front Left Chest</option> <option value="Front_Right_Chest">Front Right Chest</option> <option value="Left_Sleeve">Left Sleeve</option> <option value="Right_Sleeve">Right Sleeve</option> </select></label> </div> <div class="locations-colors pc-col quote-sizes"> <label for="color_four"><span>Number of Colors</span> <select name="color_four" id="color_four"> <option value="">choose colors</option> <option value="1">One Color</option> <option value="2">Two Colors</option> <option value="3">Three Colors</option> <option value="4">Four Colors</option> </select></label> </div> </div><br /> <div class="pc-row"> <div class="pc-col"> <div id="add-location"><a href="javascript:void(0);" class="addonemore">Add one more location</a></div> <div id="rm-location"><a href="javascript:void(0);" class="rmone">Remove one location</a></div> </div> </div> .pc-row {width: 100%;
