You simply need to remove v-bind     from selected and required attributes  Like this  -   x000D   x000D   lt template gt  x000D       lt select class  form-control  v-model  selected  required  change  changeLocation  gt  x000D           lt option selected gt Choose Province lt  option gt  x000D           lt option v-for  option in options  v-bind value  option id   gt    option name    lt  option gt  x000D       lt  select gt  x000D   lt  template gt  x000D   x000D   x000D    You are not binding anything to the vue instance through these attributes thats why it is giving error

The simplest answer is to set the selected option to true or false    lt option  selected  selectedDay     1  value  1  gt 1 lt  option gt    Where the data object is   data         return           selectedDay   1               1  2  3       31          days  Array from   length  31     v  i    gt  i  slice 1            This is an example to set the selected month day    lt select v-model  selectedDay  style  width 10    gt       lt option v-for  day in days   selected  selectedDay     day  gt    day    lt  option gt   lt  select gt    On your data set         data             selectedDay  1              1  2  3       31          days  Array from   length  31     v  i    gt  i  slice 1             mounted              let selectedDay   new Date            this selectedDay   selectedDay getDate       Sets selectedDay to the today s number of the month

Handling the errors  You are binding properties to nothing   required in    lt select class  form-control  v-model  selected   required  change  changeLocation  gt    and  selected in   lt option  selected gt Choose Province lt  option gt    If you set the code like so  your errors should be gone    lt template gt     lt select class  form-control  v-model  selected   required  change  changeLocation  gt       lt option gt Choose Province lt  option gt       lt option v-for  option in options  v-bind value  option id   gt    option name    lt  option gt    lt  select gt   lt  template gt    Getting the select tags to have a default value   you would now need to have a data property called selected so that v-model works  So       data          return         selected   Choose Province               If that seems like too much work  you can also do it like    lt template gt     lt select class  form-control   required  true   change  changeLocation  gt      lt option  selected  true  gt Choose Province lt  option gt      lt option v-for  option in options  v-bind value  option id   gt    option name    lt  option gt     lt  select gt   lt  template gt       When to use which method    You can use the v-model approach if your default value depends on some data property  You can go for the second method if your default selected value happens to be the first option  You can also handle it programmatically by doing so    lt select class  form-control   required  true  gt     lt option     v-for  option in options      v-bind value  option id      selected  option      lt the default value you want gt       gt    option    lt  option gt   lt  select gt
