/**
*
* `datalist` upgrade:
* the value submitted won't be the `value` attribute but the `data-value` attribute
* a `data-strict` attribute if set will return undefined if input value is not from data-value else it will return the input value if not foudn in options
* ex:
* ```html
* <input name="listing" list="list" data-strict/>
* <datalist id="list">
* <option data-value="value submitted" value="shown value">value subtitle</option>
* <option data-value="value submitted" value="shown valuee">value subtitle</option>
* <option data-value="value submitted" value="shown valueq">value subtitle</option>
* <option data-value="value submitted" value="shown valuea">value subtitle</option>
* </datalist>
* ```
* **ATTENTION if multiple `option` has the same `value` attribute the `data-value` will be the one of the first one**
*
*
* a `data-ignore` attribute:
* the input with the data-ignore won't send datas to server _still need the `name` attribute_
* awesome for usage with `data-autoset`
*
* a `data-regex` attribute:
* when the element is getting verified it will be passed through the regex
* ex:
* ```html
* <!-- value is set by the user -->
* <input type="text" value="00" data-regex="\d" />
* <!-- test passed form will submit -->
* <input type="text" value="O0" data-regex="\d" />
* <!-- error regex not corresponding form won't submit -->
* ```
* _please note that you still have to verify that server-side_
*
*
* a `data-default` attribute:
* if the value is not something controlable by html it will be set by here
* depending on the input type different defaults are possibles
* ex: `date` `datetime` `time` if it's set it will be the current time
* ```html
* <input type="date" name="date" data-default />
* <!-- will result if today was the 2019-08-26 in -->
* <input type="date" name="date" data-default value="2019-08-26"/>
* ```
*
*
* a `data-autoset` attribute:
* this attribute will change it's value regarding other inputs
* DON'T name any input `x` as it will break the repeat element
* (you SHOULD use `readonly` or `disabled` attribute with it)
* ex:
* ```html
* <input name="input"/>
* <input name="test" readonly data-autoset="testing-autoset-{input}"/>
* ```
* the test input should always contain `testing-autoset-(the value of input)
*
*
* a `repeat` type:
* container: `.form-manager-repeat`
* template (in container): `.form-manager-template`
* add button (in container): `.form-manager-add-button`
* delete button (in template): `.form-manager-delete-button`
*
* input MUST have data-name and not name attributes
* if the script detect `[x]` it will be replaced by `[${index}]`
* on item deletion all items are re-indexed
* if `data-default` or `data-autoset` contains `{x}` it will be replaced by `${index}`
*
* check if input has attribute `form` and that the value is the current form id
* if so add it to current form
* ```html
* <div class="fm-repeat" name="testName">
* <div class="fmr-template">
* <input data-input type="text"/>
* <!-- if there is only one input the name will be `testName[x]` -->
* <!-- if there is only multiple inputs the name will be `testName[x][index]` -->
* <div class="fmr-del">
* <button></button>
* </div>
* </div>
* <!-- future content position -->
* <div class="">
* <input data-input type="text"/>
* <div class="fmr-del">
* <button></button>
* </div>
* </div>
* <!-- future content position -->
* <div class="fmr-add">
* <button></button>
* </div>
* </div>
* ```
