I'm working with J2EE Spring boot jpa and thymeleaf I have a form (thymeleaf) when I click on an add button a table will be created dynamically with javascript, a line contains several select dropdowns how do I assign the values selected in the dropdown to a thymeleaf field
the html form:
<form th:object="${order}" method="post" th:action="@{'/order'}">
<table id="myTable2" >
<tr id="initialRow1" class="select_row">
<td> <button type="button" onClick ="addRow(this)">Add</button>
<label> Adultes</label>
<select id="select8" class="select1">
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option
><option>5</option>
<option>6</option>
</select>
<label>Enfatns</label>
<select id="idS" class="select2" onchange="myFunction()">
<option value="0">0</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option></select></td>
</tr>
